baleineau, I guess we understand each other
I remember Martina Navratilova (who knows a little about serve and volley) saying once that you don't need to hit a great volley, a good volley is enough.
I think it's the way tennis is taught this day, to get the winner as soon as you can. The same way that players can construct point from the baseline, they can and should construct point at the net.
Of course, the requires a lot of practice, and a lot of skill, and there is a very important factor that is the "sense" of the net, that only is developped through practice. If a player wants quick results, I don't recommend this style.
Height and reach are certainly assets but not the only ones. Yes, Lindsay Davenport is tall, with good reach and a good serve, can she be a serve and volley? in a word NO, she is too slow and it's very important to get to the net quickly, and she doesn't "feel" the net, sure, she has good hands and can put away a volley but from that to be a serve and volleyers there is a big difference.
Neither can Venus IMO, at least not now, she has a powerful serve, and reach, but again, to be a serve and volleyer requires time, risk assumption and a mind set.
The thought that short players can't come to the net because they can be passed through lobs or passing shots is a myth. Anyone can be passed with a low, the key is to make it difficult for the opponent to hit a good lob, and to sense when the opponent is going to do that, not to be tall.
Again, look at Pat Rafter, he seems to know where the ball is going, crosscourt, dtl, a lob, he anticipates and covers the net, reach? not really, he moves to reach the ball and to get the best angle, and that's another mistake, most players tend to be static at the net.
Now, how does Pat Rafter "know" where the ball goes? well, partly is that net "sense", call it experience, and partly is because a good serve and volleyer will dictate how the point is gonna be played, if he hits a good approach shot, he limits the option the opponent has, and just looking at the opponent, and hearing the ball he can "predict" where it's going.
Ever wondered why serve and volley is said to be suitable for fast surfaces?, because it gives the other player less time to set up the shot. The passing shot, or the lob has to be instintive and that makes it predictible, if you give your opponent time, you can be as tall as you want but you are gonna get passed.
